How do you eat a whale? A little at a time. Try not to see the whole thing and start with the easy stuff. Sort your clothes by color (lights/darks) and toss them in the machine if you have one in your apartment. While you're waiting, you can go through your closets to reorganize. My rule of thumb, if I haven't seen it for over a year and I don't need it - toss it or donate it. If you don't have boxes to throw nicknacks in just do your best to stack it. A tidy mess is easier to look at than a random mess. As for the paper work, skim through it but if you're running out of time, stack them neatly and it shouldn't be a problem. If you don't feel like folding your clothes then you can always bag them like Perna said. I hope you enjoy ironing.

Might help to make a list of things to do - it's motivational when you cross something off. Keep it detailed and not broad so you have more opportunities to check it. Just remember to breathe Don't try to do it all at once though.
